I beg to disagree. I preferred the VOC long over NUVOC, but that was more since I got used to VOC during a rather steep learning curve. And because the VOC is out of date after the new releases came up (with an impressive frequency), you, well, in any case I, don't have any choice. Now I get used to NUVOC, I appreciate its style and admire the work which people have put in it. Once and a while I glance back in the VOC, just to be sure about an example given there.
